Stopping Power (again?)

Get a gun/cartridge combination that goes bang every time you pull the trigger and which you can shoot quickly and accurately. No common defensive handgun cartridge will quickly and reliably stop a human being who is committed to causing serious bodily harm, unless the bullet from that cartridge is applied to the correct anatomy. When the bullet is applied to the correct anatomy ANY of the 3 will serve equally well (9mm, .40, .45).

Get gun in a caliber of 9mm/.38 or larger. Shoot gun lots and lots. Problem solved.

Well when I got back in to guns after a considerable period without having any, I went with nine millimeter because of the price factor. Surplus Star BM’s were dirt cheap at the time.
Any shortcomings 9mm may have compared to other calibers was insignifigant to me at that point, because that old Star was a serious upgrade over curse words, left hooks, and a baseball bat.
